Which one fits you

On wrists narrower than about 46mm, the Active is the safer pick — it stays proportionate down to roughly 38mm, where the Active 2 starts to hang over the edge. Above 46mm both sit cleanly, and the Active 2 gives you more presence.

The Active 2 wears larger than the Active (43.9mm vs 42.36mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Active 2 is the slimmer of the two (9.9mm vs 10.75mm), so it slides under a cuff more easily.

On the wrist the Active feels lighter (27g vs 29.5g, case only).

The Active is thinner than 87% of the 42mm watches we track and the Active 2 than 99% of the 44mm ones — so both wear flatter than their widths suggest.

The Active 2 is 1.5mm wider, 8mm longer, 0.8mm thinner and 2.5g heavier than the Active.

Watch Fit Tool

For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.

Understated

35.9mm on a 55mm wrist

10:09TUE 12lug to lug 35.9mmyour wrist 55.0mm

Well inside your wrist on every measurement — you have room to go a size up if you want more presence.

On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 35.9mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
  2. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
